He, of course, made no move to hand it back. If Jetfire wanted it, he would have to forcefully take it from him. And in attempt to fully change the subject he went on to answer the question about the box.

"Oh, that? That is for you."

He offered no further explanation and stood up to move towards the berth where he intended to plop down. Starscream had a hard time sitting in one place for too long -- unless he was recharging, which almost seemed like a good idea.

And yes, he intended to take the piece of metal with him.
